Efficient Approach to Solving Transient Unsaturated Flow Problems. I: Analytical Solutions
(American Society of Civil Engineers, 2017)Richard’s equation governs the migration of moisture in the soil under unsaturated conditions. Although this differential equation provides a rigorous approach to simulating important infiltration problems, obtaining ... -
Disturbed State Concept–Based Constitutive Model for Structured Soils
(American Society of Civil Engineers, 2017)The compression behavior of structured soils after virgin yielding is highly nonlinear and cannot be captured by a single line in the e–ln(p′) space. The slope of the compression curve of structured soils changes gradually ... -
Immediate Estimation of Yield Acceleration for Shallow and Deep Failures in Slope-Stability Analyses
(American Society of Civil Engineers, 2017)The accurate assessment of the stability of natural slopes and earth structures during earthquakes is a critical design aspect for seismically active areas. The Newmark-type displacement method, which is capable of estimating ... -
Discussion of “Seismic Uplift Capacity of Horizontal Strip Anchors Using a Modified Pseudodynamic Approach” by Anindya Pain, Deepankar Choudhury, and S. K. Bhattacharyya
(American Society of Civil Engineers, 2017) -
3D Limit Analysis of Progressive Collapse in Partly Weathered Hoek–Brown Rock Banks
(American Society of Civil Engineers, 2017)Because of the heterogeneous layered characteristics of geomaterials, analysis of tunnel stability may be complicated, and such characteristics increase the possibility of progressive failure of the surrounding rock banks. ... -
Influence of SSI on Period and Damping of Buildings Supported by Shallow Foundations on Cohesionless Soil
(American Society of Civil Engineers, 2017)This study investigates the influence of soil–structure interaction (SSI) on period and damping of steel moment-resisting frame buildings supported by shallow footings on dry sand deposits. A series of impact hammer tests ... -
Similarity Relationship for Brittle Failure Dynamic Model Experiment and Its Application to a Concrete Dam Subjected to Explosive Load
(American Society of Civil Engineers, 2017)This paper suggests that the idea of the breaking strength of the brittle material scale being equal to the length scale was abandoned in the dynamic model brittle failure experiments. The concept of the failure load ... -
Influence of Heating Rate on the Dynamic Mechanical Performance of Coal Measure Rocks

Time-Frequency Analysis of Seismic Wave Propagation across a Rock Mass Using the Discontinuous Deformation Analysis Method
(American Society of Civil Engineers, 2017)To investigate the wave (including P-wave and S-wave) propagation across a rock mass, the seismic discontinuous deformation analysis (DDA) method is used, and a time-frequency analysis of the DDA simulation results is ... -
Analysis of Different Types of Heterogeneity and Induced Stresses in an Initially Stressed Irregular Transversely Isotropic Rock Medium Subjected to Dynamic Load
(American Society of Civil Engineers, 2017)In this study, the closed-form expressions of the incremental stresses (normal and shear) induced by a load moving at a constant speed in a rock medium containing free surface were obtained analytically. The closed-form ... -
Investigation of Sloped Surface Subsidence during Inclined Seam Extraction in a Jointed Rock Mass Using Discontinuous Deformation Analysis
(American Society of Civil Engineers, 2017)In this study, the sloped ground subsidence of a jointed rock mass during tilted seam extraction was investigated using a trap-door model and discontinuous deformation analysis (DDA). In the trap-door model, the jointed ... -
Numerical Modeling of the Geomechanical Behavior of Biyadh Reservoir Undergoing CO<sub>2</sub> Injection
(American Society of Civil Engineers, 2017)Sequestration of CO2 in deep sedimentary reservoirs is one of the potential methods that can be used for reducing the level of CO2 in the atmosphere. In this investigation, a geomechanical modeling study was performed for ... -
Seismic Passive Resistance of Cohesive-Frictional Soil Medium: Kinematic Limit Analysis
(American Society of Civil Engineers, 2017)In the present study, extensive theoretical solutions in the form of charts have been generated based on a kinematically admissible translational mechanism for computing the passive resistance of cohesive-frictional soil ... -
Revisiting the Calibration Philosophy of Constitutive Models in Geomechanics
(American Society of Civil Engineers, 2017)Conventional laboratory tests in geomechanics are inherently designed to create a uniform stress–strain field whereby relative homogeneity in data prevails at the expense of information diversity. The one-element convenience ... -
Fracture-Induced Anisotropy of the Stress–Strain Response of Shale at Multiple Scales
(American Society of Civil Engineers, 2017)This paper investigates deformation and stiffness anisotropy induced by damage propagation in a rock brittle deformation regime. Specifically, a finite-element–based Continuum damage mechanics model is used to capture ... -
Model Uncertainty for Predicting the Bearing Capacity of Sand Overlying Clay
(American Society of Civil Engineers, 2017)In this paper, 62 centrifuge tests are collected from the literature and used to perform a statistical evaluation of the model factor for conventional methods to calculate the bearing capacity of dense sand overlying clay. ... -

Three-Dimensional Failure Criteria for Rocks Based on the Hoek–Brown Criterion and a General Lode Dependence
(American Society of Civil Engineers, 2017)Three-dimensional (3D) failure criteria based on the Hoek–Brown (HB) criterion and a general Lode dependence for rocks were proposed in this paper. The proposed failure criteria inherited the compression meridian from the ...
